To all whom. it may concern:

Belt known that I, Anonr Dnernn, engi neer", citizen of Germany, subject of the King of Prussia. and lhnperor of Germany, residing at Potsdam, Kanal 10, in the Kingdom of Prussia and Empire of Germany, have invented'certnin new and useful Improvements'in Bottle-Closures, of which the following is e. full, clear, and exact description.

My invention relates to improvements in bottle closures and has for its ol)ject,first,"t0 provide a closure adapted to be seated in a bottle neck and to permit the free discharge of any liquid as liquor, cognac, etc, from the filled bottle, but to prevent refilling of same with a liquid of inferior value, when once 12' will empty, and second to leave the closure intact in case of breaking the neck of the bottle, after the same having been emptied, render ing thereby the closing device capable of being reused as often as occnsionis desired.

The present invention consists in a combination 51nd arrangement of parts as hereinafter more fully described, shown in the aobompanyin drawings and pointed out in the eppende claim.

The improved invention relates to that class of bottle closures for non re-fillnble bot- .tles which are secured inithe bottle neck and can onl be removed after breaking the neck of the ottle- According to the present inve'ntion however, a new result is obtained in that the closure prevents: 'a refilling of the inverted bottle by means of a compressed liquid.

A bottle closure embodying my. invention is illustrated in the accompanying drawing in which:

-Figure 1 is 11 vertical sectional view of the improved bottle closure. Fig. 2 is a view of the improved bottle closure shown in side elevation mounted in the neck of a bottle shown in vertical section. Fig. 3 is a horizontal sectional View of the improved bottle closure.

The special features of the invention lie in the arrangement of the main canals 2, 3, formed in theneclr of the bottle, the shorter connecting canals 17, 18 formed in a. rigidly seated stopper or plug 6 and converging to a. central cavity or cup 11, the canals 17, 18, extending inwardly in the lug 6 and communicating with the channe s 2, 3, formed in the bottle neck and the spherical valve 12, having vertical movement or cavity or cup 11. All these cane s must have lay in the" the same sectional area; the length however,

of the canals 2, 3, together with the length of the connecting canals 15, 16 formed in the plug 6 and communicating with the central cavity 11 must be double the length of the second canals 17, 18 which run directly into the hollow cup 11 and meet in the center of the plug.

When the bottle is inverted, the valve 12 will fall into the bottom of the cavity 11 which forms a cup to receive it, and will close the opening into said cup from the canals 17, 18, but will be below the inner ends of the channels 15, 1G. The contents of the bottle will then flow out through the channels l5 16-2, 3. The position the, valve take when the bottle has been reversed, is'shown b dotted lines (see Fig. 1).

Any,refilling 0% the bottle by compressed liquid is now prevented for the reason that the compressed liquid seeks first its way through the short directly running canals 1718, below the valve 12' pressing it u wardly a little easily be and the inner en s of the canals 15, 16 as t e valve is made of glass or a. non-oxidable substance without any great wei ht; this permits a joinin of the streams o compressed liquid through all the canals, thus pressing the valve u Ward with more force and causin the va ve to rest against the seat 13, there y closin tl1e.opening 14 so that no liquid can pass through the opening 14 into the bottle.

To secure the plu 6 in place in the neck of theoottle, and a low the contents to be poured out, the plug is formed with :1 diametrical channel in which are fitted bolts 9, 10, and an intervening spiral spring 8, which presses the bolts outwardl To receive these bolts the bottle neck is ormed with interior segmental, horizontally arranged channels 45. When the plug 6 is inserted these bolts project into the channels 4, 5, and prevent the plug from being withdrawn. The plug however, can be turned around so as to close or open the bottle at will for the outflow of the iquid.

The channels 2, 3, communicate with the channels 15, 16-17, 18 only in one osition of the plug, as when all the charms s lie in the same vertical plane, partially shown in Figs. 1' and 3, and thecont'entsof the bottle can only be oured out when such communication is e ected by turnin the plug 6. In an other position of the p ug the bottle is see ed.

Having thus described the invention, what I claim is:

The combination with a bottle having downwardly extending open sided channels on the interior of its neck, with open ends at the month of the bottle, of a rotatable plug having a central cavity in its lower part, and two series of channels communicating therewith, each series communicating with the channels in the bottle neck but at different levels from the other series, whereby the course of travel of ii aid from the inlet of the. last named channe s to the central cavity will be longer through one series than through the other; a sp erical valve located in the cavity, a valve seat in the plug at the lower end of the cavity, the arts being so disposed that when liquid is orced into the said channels while the bottle is inverted it will first press on the lowest part of the .valve, and raise the same so as to open all the channels and cause, the valve to impinge against its seat and prevent ingress of liquid. In witness whereof, I subscribe my signature, in presence of two witnesses.
